Final Lesson

Next we dove into the final lesson of this unit. It turned out to be a fairly easy one for me, I felt like I understood it pretty well. We were learning about percent composition and empirical formulas. I remember seeing empirical formulas on the pretest and wondering what in the world that was, but now I knew that it was the lowest whole number ratio of elements in a compound.  We compared and contrasted empirical formulas to molecular formulas, and I ended up taking about 3 pages of notes which is pretty crazy. Even though it was a lot to take in, I felt pretty confident that I could do these kind of problems on the test coming up, but I need to do some more practice.
